IMPROVEMENT IN BOX-OPENERS.

'lO ALL WHOM IT MAY CONCERNE Be it known that I, Jem; WILLARD, of Norwich, in the county of New London, and State of Connecticut, have invented a new and useful Improvement ing Chisels-for Opening Boxes, and other purposes; and I .do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, in which the chisel is shown in elevation, parts being represented in section.

My improvement, as illustrated, relates to a chisel, such as is used in opening boxes, but, by altering the form of the point, it may be applied to other uses, such as e carpenter-s mortisingtchisel, an engravers chisel, cold-chisel, or otlieranalogous uses. l

The invention consists in attaching to the chisel-point a hollow stock or handle, Within which si loaded plunger plays, which may be driven against the base of the socket, and usedinstead of n. hammer in working with the chisel.

In the ,annexed drawing, I have shown, at A, the point of a. chisel, such as is used in opening boxes. The form of the point is, however, not essential, ns it may be varied to adapt it to other uses. B is the stock or handle of the chisel. Theupper portion, shown in section at Bl, is tubular, and receives the rod C, ,having the head C so arranged as to rest upon the hase of the socket in the handle, as shown. The rod passes through a hole in the collar or flange B2, which prevents thc bend C frombeing d'rawn out of the socket, and directs the action of the rod in the line of the handle.

A ball or other knob, D, is fastened to the outer end of the rod C. The weight of this knob, as Wel-l as the proportions ofthe other parts of thc chisel, must, of course, be made dependent upon vthe character of the Work to which it is intended to apply the tool. The knob being held in one hand, the tool is to be properly directed with the other, when, by striking the head C against the bottom of the socket, the chisel will he driven as by a hammerrbut always in a right line with the stock and point, and with a force c apable of exact regulation.

What I claim as lmy invention, and desire to secure by Letters Patent, is

The combination of the chisel-point A, the tubular handle B, and the weighted rod 0, constructed and arrangedto operate substantially as set forth, as an article of manufacture.

In testimony whereof, I have signed my name to this specification in the presence of two subscrbingfwitnesses.

JOHN WILLARD.
